[DECRYPTAGE] Numerical simulation of 4D flow MRI

Historically reserved for morphological studies, technological advances over the last few decades have made it possible to adapt Magnetic Resonance Imaging (MRI) to the exploration of blood flow, thanks to 3D phase contrast MRI (or 4D flow MRI) [1]. By providing access to the temporal evolution of the velocity field in all three spatial directions, in addition to the morphology of the arterial sector of interest, it is a tool of choice in clinical practice for the management and monitoring of patients with pathologies related to hemodynamics.

[DECRYPTAGE] MRI & pregnancy: what are the risks associated with electromagnetic fields and Gadolinium?

Magnetic Resonance Imaging (MRI) is the modality of choice for the study of many pathologies, as it can produce very high quality images without exposure to ionizing radiation. However, this imaging technique is not without its risks.
